I couldn't agree more! Nose heavy planes have a hard time of bleeding off the speed that a more neutral plane has no problem burning. A plane with a neutral CG will be able to pick the nose up and come in in a VERY slight harrier. Full-scale planes do this. Your descent is NOT controlled by your elevator...it's controlled by your throttle.

To answer your question, though....lighter planes are more stable (except in heavy winds, but that's not a can of worms I'd advise opening up).
